CARBURETER FOR EXPLOSIVE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 659,987', dated octane;r-` 16, '1900.

Application filed August 2,1899. Serial No. 725,885. (No model.)

To cir/ZZ whom, t uta/y concern:

Be it known that I, HUBERT CARLISLE RAY, of Visalia, in the county of Tulare and State of California, have invented a new and Improved Carbureter for Explosion-Engines, of which the following is a full, clear, and exact description.

My invention relates to an improvement in devices for producing gas from oils, and is designed for use in connection with explosionengines, the object of the device being to enable crude oils to be used instead of refined petroleum or gasolene.

My invention comprises the novel features which are hereinafter described and claimed.

Reference is to be had to the accompanying drawing, forming a part of this specication, in which the figure shows the upper or cylinder end of a gas-engine having my device attached thereto, the carbu reter being shown in section.

My device is herein shown as applied to a vertical gas-engine, although the method of its attachment may be widely varied according to the circumstances of each particular case, yet the principle of this application is sufficiently illustrated.

In the drawing, A represents the cylinder of the gas-engine, and B the pipe through which the exhaust or waste gases from the engine are discharged. This pipe is provided with an extension C, which passes centrally through a carbureting-chamber or oil-tank E, which is located above the enginecylinder. This carbureter or oiletank is supplied with a certain amount of oil, which is ordinarily sufficient to only partially fill the tank. Oil is supplied to this tank from a reservoir or tank G, which is located at any convenient and safe point and at a slightly-greater elevation than the point where it is desired to maintain the oil in the carbureter E. This tank G is connected with the carbureter by means of a pipe I, which is provided with a check-valve I and an ordinary throttle-valve I2. The carbureter may be provided with a gage-glass e, which will indicate the exact level of oil therein. The suction through the pipe F will draw oil through the valve I, which latter can be set to regulate the amount of oil entering the carbureter.

A pipe D has the lower end D2` thereof extending upward within the exhaust-chamber B of the engine and connecting with the outer air by a side opening d', and by this means the air passing through the pipe D2 is heated. The upper end of the pipe D preferably exwtends slightly above the top of the carbureter-tauk, forming a curve or bend d, the end D extending downwardly within said tank and terminating near the bottom thereof and below the level of the oil therein, so that air passing through the pipe D bubbles up through the oil and becomes charged with the vapors of the oil. The exhaust passing upwardly through the pipe C and the carbureter heats the contents thereof, so that the oil becomes very volatile, and the air passing upwardly through the same becomes heavily charged. The constant agitation of the oil caused by the air passing through it makes it give off easily all its volatile parts, and the agitation also prevents caking from heat of the residue in the carbureter; also, the hot air helps to heat the oil. This charged air is drawn off through a pipe F, the upper end of which preferably lies within an upward eX- tension E of the tank, so as to make sure that none of the oil will be drawn through into this pipe. The pipe F extends downward and connects with the supply-passages of the engine. The upper portion of the carbureter E is connected with the reserve-tank Gr by means of a pipe H, which is provided with a check-valve 7L at any convenient point, preventing flow of air or oil from the reservetank to the carbureter through this pipe. If the oil in the carbureter should become eX- cessively heated and an amount of gas should thereby be generated greater than is being used, the surplus gas will pass through the pipe H to the reserve-tank, and as the end of the pipe H extends beneath the level of oil in said tank the gases will be forced to bubble up through the oil, and as this tank is located where it will be kept cool the gases will be condensed and no loss will occur. This forms a safety device to prevent generation of excessive pressure.

A pipe F is connected with the pipe F and is provided with a throttlingvalvef,by means of which connection may be made with asup IOO ply of gas-orkgasolene `for operatiouin-the ordinary fmann'er viihen the engine 4iis rst' started.

In operating an engine having mydeviee attached thereto it will be necessary, if crude oil is being usedftooperatemhe engine ashortf time before the carbureter'is Tbrought into use. For this purpose the pipe F is supplied and ordinary gas orgasolene, which .Willvaporiz'e readily, is first used. After the engine has been running a short time and the ex-V haust has heated lthe oil in the :carbureter the valve fis closed and the supplyof explo, sive mixture is drawn fromthe earbureter'E.

A valve J is connected with the bottom of the carbureter,so that theresidue and heavier portions of the oil left after volatilizing the: lighter portions maybe drawn off and the carbureter cleaned.

With this device itis possible to use crude,` petroleum and other :similar hydrocarbons,` thus materially redueingt'he cost of fuel.

Having thus fully described my invention, I claim as'new and desire to secure by Letters Patentl. Acarbureter for explosive-engines, 'com-y` prising a carbureting-tank, means vforheating said tank, an oil-supply tank connected: with said carbureting-tank,'and a `pipelead-I ing from the gas-space ofthe carbureting-tank to-the oil-supply tank, said `pipe being provided with a safety-valve, substantially as setl A forth.

2. A earbureter for explosion-engines, comprlsing an oil-tank having passages therein Y for receiving the engine exhaust whereby itsA contents are heated, an air-supply pipe hav-` ing-itadischargeendfprojectingbeneath the oiliin thetarik and itsfother end drawing air through passages heated by the engine, an engine-supply pipe extending from the top of said tank, and an oil-supply tank having an oil-feedingpipe eonnectedwiththe carbureter and provided with a back-pressure valve, and a pipe leading from the top of the carbureter itobeneath the o'ilin the su ppiy-tank and pro- -pipe for conveying oil to the carbureter, and

apipe leading fromthe gas-space yof the carbureter tobeneath the oililevelin thesupplytank and provided with a safety-valve, substantially as specified.
